I keep a close watch on this heart of mine. I keep my eyes wide open all the time. I keep the ends out for the tie that binds. Because you're mine, I walk the line.

I find it very, very easy to be true. I find myself alone when each day is through. Yes, I'll admit I'm a fool for you. Because you're mine, I walk the line.

As sure as night is dark and day is light. I keep you on my mind both day and night. And happiness I've known proves that it's right Because you're mine, I walk the line.

You've got a way to keep me on your side. You give me cause for love that I can't hide. For you I know I'd even try to turn the tide. Because you're mine, I walk the line.
